Common instructions for analyzing the use of PHPExcel and an introduction to integrating PHPExcel into the CI framework_PHP Tutorial

Excel writing and generating operations:

Copy code The code is as follows:

include 'PHPExcel.php';
include 'PHPExcel/Writer/Excel2007.php';
//或者include 'PHPExcel/Writer/Excel5.php'; 用于输出.xls的
include 'PHPExcel/IOFactory.php';//phpexcel工厂类
//创建一个excel
$objPHPExcel = new PHPExcel();
//保存excel—2007格式
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);
//也可以使用
//$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, "Excel2007");
//或者$objWriter = new PHPExcel_Writer_Excel5($objPHPExcel); 非2007格式
$objWriter->save("xxx.xlsx");
//直接输出到浏览器
$objWriter = new PHPExcel_Writer_Excel5($objPHPExcel);

//合并单元格
$objPHPExcel->getActiveSheet()->mergeCells('A18:E22');
//分离单元格
$objPHPExcel->getActiveSheet()->unmergeCells('A28:B28');
//保护cell
$objPHPExcel->getActiveSheet()->getProtection()->setSheet(true); // Needs to be set to true in order to enable any worksheet protection!
$objPHPExcel->getActiveSheet()->protectCells('A3:E13', 'PHPExcel');
//设置格式
// Set cell number formats
echo date('H:i:s') . " Set cell number formats\n";
$objPHPExcel->getActiveSheet()->getStyle('E4')->getNumberFormat()->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_CURRENCY_EUR_SIMPLE);
$objPHPExcel->getActiveSheet()->duplicateStyle( $objPHPExcel->getActiveSheet()->getStyle('E4'), 'E5:E13' );
//设置宽width
// Set column widths
$objPHPExcel->getActiveSheet()->getColumnDimension('B')->setAutoSize(true);
$objPHPExcel->getActiveSheet()->getColumnDimension('D')->setWidth(12);
//设置font
$objPHPExcel->getActiveSheet()->getStyle('B1')->getFont()->setName('Candara');
$objPHPExcel->getActiveSheet()->getStyle('B1')->getFont()->setSize(20);
$objPHPExcel->getActiveSheet()->getStyle('B1')->getFont()->setBold(true);
$objPHPExcel->getActiveSheet()->getStyle('B1')->getFont()->setUnderline(PHPExcel_Style_Font::UNDERLINE_SINGLE);
$objPHPExcel->getActiveSheet()->getStyle('B1')->getFont()->getColor()->setARGB(PHPExcel_Style_Color::COLOR_WHITE);
$objPHPExcel->getActiveSheet()->getStyle('E1')->getFont()->getColor()->setARGB(PHPExcel_Style_Color::COLOR_WHITE);
$objPHPExcel->getActiveSheet()->getStyle('D13')->getFont()->setBold(true);
$objPHPExcel->getActiveSheet()->getStyle('E13')->getFont()->setBold(true);

$objPHPExcel->getActiveSheet()->getStyle('D11')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_RIGHT);
$objPHPExcel->getActiveSheet()->getStyle('D12')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_RIGHT);
$objPHPExcel->getActiveSheet()->getStyle('D13')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_RIGHT);
$objPHPExcel->getActiveSheet()->getStyle('A18')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_JUSTIFY);
//垂直居中
$objPHPExcel->getActiveSheet()->getStyle('A18')->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER);
设置column的border
$objPHPExcel->getActiveSheet()->getStyle('A4')->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
$objPHPExcel->getActiveSheet()->getStyle('B4')->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
$objPHPExcel->getActiveSheet()->getStyle('C4')->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
$objPHPExcel->getActiveSheet()->getStyle('D4')->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
$objPHPExcel->getActiveSheet()->getStyle('E4')->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
设置border的color
$objPHPExcel->getActiveSheet()->getStyle('D13')->getBorders()->getLeft()->getColor()->setARGB('FF993300');
$objPHPExcel->getActiveSheet()->getStyle('D13')->getBorders()->getTop()->getColor()->setARGB('FF993300');
$objPHPExcel->getActiveSheet()->getStyle('D13')->getBorders()->getBottom()->getColor()->setARGB('FF993300');
$objPHPExcel->getActiveSheet()->getStyle('E13')->getBorders()->getTop()->getColor()->setARGB('FF993300');
$objPHPExcel->getActiveSheet()->getStyle('E13')->getBorders()->getBottom()->getColor()->setARGB('FF993300');
$objPHPExcel->getActiveSheet()->getStyle('E13')->getBorders()->getRight()->getColor()->setARGB('FF993300');
设置填充颜色
$objPHPExcel->getActiveSheet()->getStyle('A1')->getFill()->setFillType(PHPExcel_Style_Fill::FILL_SOLID);
$objPHPExcel->getActiveSheet()->getStyle('A1')->getFill()->getStartColor()->setARGB('FF808080');
$objPHPExcel->getActiveSheet()->getStyle('B1')->getFill()->setFillType(PHPExcel_Style_Fill::FILL_SOLID);
$objPHPExcel->getActiveSheet()->getStyle('B1')->getFill()->getStartColor()->setARGB('FF808080');
//加图片
$objDrawing = new PHPExcel_Worksheet_Drawing();
$objDrawing->setName('Logo');
$objDrawing->setDescription('Logo');
$objDrawing->setPath('./images/officelogo.jpg');
$objDrawing->setHeight(36);
$objDrawing->setWorksheet($objPHPExcel->getActiveSheet());
$objDrawing = new PHPExcel_Worksheet_Drawing();
$objDrawing->setName('Paid');
$objDrawing->setDescription('Paid');
$objDrawing->setPath('./images/paid.png');
$objDrawing->setCoordinates('B15');
$objDrawing->setOffsetX(110);
$objDrawing->setRotation(25);
$objDrawing->getShadow()->setVisible(true);
$objDrawing->getShadow()->setDirection(45);
$objDrawing->setWorksheet($objPHPExcel->getActiveSheet());
//处理中文输出问题
//需要将字符串转化为UTF-8编码，才能正常输出，否则中文字符将输出为空白，如下处理：
 $str  = iconv('gb2312', 'utf-8', $str);
或者你可以写一个函数专门处理中文字符串：
function convertUTF8($str)
{
   if(empty($str)) return '';
   return  iconv('gb2312', 'utf-8', $str);
}

读取excel
1.导入一个Excel最简单的方法是使用PHPExel的IO Factory，调用PHPExcel_IOFactory类的静态法load，它可以自动识别文档格式，包括Excel2007、Excel2003XML、OOCalcSYLK、Gnumeric、CSV。返回一个PHPExcel的实例。
 

复制代码 代码如下:

//Load the factory class
include'PHPExcel/IOFactory.php';
//The path of the xls file to be read
$inputFileName = './sampleData/example1.xls' ;
/**Use the load method of PHPExcel_IOFactory to get the excel operation object **/
$objPHPExcel = PHPExcel_IOFactory::load($inputFileName);
//Get the current active table, call the toArray method, and get the two-dimensional array of the table
$sheetData =$objPHPExcel->getActiveSheet()->toArray(null,true,true,true);
var_dump($sheetData);

1. Create a ExcelReader to load an Excel document
If you know the format of this Excel document, you can create a corresponding Reader to load the Excel document to be read. But if you load the wrong document type, unpredictable errors may occur.

Copy code The code is as follows:

$inputFileName = './sampleData/example1.xls';
/* *Create a new Excel5 Reader  **/
$objReader = new PHPExcel_Reader_Excel5();
// $objReader = new PHPExcel_Reader_Excel2007();
// $objReader = new PHPExcel_Reader_Excel2003XML();
// $objRead er = new PHPExcel_Reader_OOCalc();
// $objReader = new PHPExcel_Reader_SYLK();
// $objReader = new PHPExcel_Reader_Gnumeric();
// $objReader = new PHPExcel_Reader_CSV();
/* *Load $inputFileName to a PHPExcel Object  **/
$objPHPExcel = $objReader->load($inputFileName);
//Get the current active sheet
$curSheet =$objPHPExcel->getActiveSheet();
//Return the data of the table in the form of a two-dimensional array
$sheetData = $curSheet->toArray(null,true,true,true);
var_dump($sheetData);

You can also use the createReader method of PHPExcel_IOFactory to get a Reader object without knowing the format of the file to be read.

Copy code The code is as follows:

$inputFileType = 'Excel5';
// $inputFileType = 'Excel2007' ;
// $inputFileType = 'Excel2003XML';
// $inputFileType = 'OOCalc';
// $inputFileType = 'SYLK';
// $inputFileType = 'Gnumeric';
// $inputFileType = 'CSV';
$inputFileName = './sampleData/example1.xls';
/**  Create a new Reader of the type defined in $inputFileType  **/
$objReader = PHPExcel_IOFactory::createReader($ inputFileType);
/**   Load $inputFileName to a PHPExcel Object  **/
$objPHPExcel = $objReader->load($inputFileName);
//Get the current active sheet
$curSheet = $objPHPExcel-> ;getActiveSheet();
//Return the data of the table in the form of a two-dimensional array
$sheetData = $curSheet->toArray(null,true,true,true);
var_dump($sheetData) ;

If the file format is unknown before reading the file, you can get the file type through the identify() method of IOFactory, and then use the createReader() method to access the file reader.

Copy code The code is as follows:

$inputFileName = './sampleData/example1.xls';
/* *Determine the format of the input file **/
$inputFileType = PHPExcel_IOFactory::identify($inputFileName);
/**Wear the corresponding reader **/
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
/**Load the file to be read **/
$objPHPExcel = $objReader->load($inputFileName);

2. Set Excel’s read options
Before using the load() method to load a file, you can set reading options to control the behavior of load.
2.1. ReadingOnly Data from a Spreadsheet File
setReadDataOnly() method to configure the reader Regardless of the data type of the table data, all are returned in string format

Copy code The code is as follows:

$inputFileType = 'Excel5 ';
$inputFileName = './sampleData/example1.xls';
/**  Create a new Reader of the type defined in $inputFileType  **/
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
/** Configuration cell data are returned as strings **/
$objReader->setReadDataOnly(true);
/**   Load $inputFileName to a PHPExcel Object  **/
$objPHPExcel = $objReader->load($inputFileName);
$ sheetData =$objPHPExcel->getActiveSheet()->toArray(null,true,true,true);
var_dump($sheetData);

Return data:

Reading Only Data from a SpreadsheetFile applies to Readers:
       Excel2007      YES         Excel5            YES         Excel2003XML YES
       OOCalc          YES         SYLK              NO          Gnumeric       YES
       CSV         NO

2.2.ReadingOnly Named WorkSheets from a File
setLoadSheetsOnly(),设置要读取的worksheet，接受worksheet的名称作为参数。

复制代码 代码如下:

/**PHPExcel_IOFactory*/
include'PHPExcel/IOFactory.php';
$inputFileType = 'Excel5';
//  $inputFileType = 'Excel2007';
//  $inputFileType = 'Excel2003XML';
//  $inputFileType = 'OOCalc';
//  $inputFileType = 'Gnumeric';
$inputFileName ='./sampleData/example1.xls';
$sheetname = 'Data Sheet #2';

echo 'Loading file',pathinfo($inputFileName,PATHINFO_BASENAME),' using IOFactory with a definedreader type of ',$inputFileType,'
';
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
echo 'Loading Sheet"',$sheetname,'" only
';
$objReader->setLoadSheetsOnly($sheetname);
$objPHPExcel =$objReader->load($inputFileName);
echo '

---

';
echo$objPHPExcel->getSheetCount(),' worksheet',(($objPHPExcel->getSheetCount()== 1) ? '' : 's'),' loaded

';
$loadedSheetNames =$objPHPExcel->getSheetNames();
foreach($loadedSheetNames as$sheetIndex => $loadedSheetName) {
    echo $sheetIndex,' -> ',$loadedSheetName,'
';
}

如果想读取多个worksheet，可以传递一个数组

复制代码 代码如下:

$inputFileType = 'Excel5';
$inputFileName = './sampleData/example1.xls';
$sheetnames = array('Data Sheet #1','Data Sheet #3');
/**  Create a new Reader of the type defined in $inputFileType  **/
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
/**  Advise the Reader of which WorkSheets we want to load  **/
$objReader->setLoadSheetsOnly($sheetnames);
/**  Load $inputFileName to a PHPExcel Object  **/
$objPHPExcel = $objReader->load($inputFileName);

如果想读取所有worksheet，可以调用setLoadAllSheets()。
